Unformatted text preview: Separating Azeotropic Mixtures CHEN 4460 Process Synthesis, Simulation and Optimization Dr. Mario Richard Eden Department of Chemical Engineering Auburn University Lecture No. 6 Review of Non-ideal Thermodynamics September 27, 2011 Contains Material Developed by Dr. Daniel R. Lewin, Technion, Israel Process Design/Retrofit Steps Assess Primitive Problem Development of Base-case Plant-wide Controllability Assessment Detailed Design, Equipment sizing, Cap. Cost Estimation, Profitability Analysis, Optimization Detailed Process Synthesis -Algorithmic Methods PART II Algorithmic Methods Lecture 6 Introduction Separation sequences are complicated by the presence of azeotropes, often involving mixtures of oxygenated organic compounds: Alcohols Ketones Ethers Acids Water In these cases, distillation boundaries limit the product compositions of a column to lie within a bounded region. This prevents the removal of certain species in high concentrations. Lecture 6 Objectives Be able to sketch the residue curves on a ternary phase diagram Be able to define the range of possible product compositions using distillation, given the feed composition and the ternary phase diagram Basics: The Lever Rule Basics: Ternary Phase Diagrams 0.15 H 2 O 0.65 DTBP 0.2 TBA 0.2 DTBP Basics: Ternary Phase Diagrams 0.6 H 2 O 0.2 DTBP 0.2 TBA Homogeneous Azeotropes 1:4...
